This text explores the definition of ethics as a philosophical discipline focused primarily on the principles and rules governing human conduct rather than mere factual behavior. The author argues that ethical inquiry must distinguish between how individuals actually behave and the norms they internalize and follow. Rather than limiting itself to a descriptive account of outward actions, ethics aims to understand the standards against which these actions are measured and where they might fail. The document warns against the pitfalls of reductionism—specifically the tendency to categorize norms as either purely objective or subjective—viewing such labels as prejudices that hinder genuine understanding. Instead, the author proposes a conceptual framework that considers the non-objective dimension of human activity and true beings. Ultimately, the core philosophical challenge of ethics lies in recognizing the unique nature of moral principles as a distinct reality. To achieve this, one must abandon intellectual self-limitations and adopt means capable of addressing the complexity of human action beyond mere facticity.
